In Reply to: Exhaust manifold connecting bolts posted by Steve///M on August 29, 2001 at 01:36:28:

Look up bolts or fasteners in the good 'ol yellow pages. Then go and get some nice set-screw-type studs, i.e. the ones with the allen key thing on the ends. Then bottom them in there w/ loctite. Get some new lock nuts.

The reason I say to get the set-screw kind is that they are much easier to use and you can be more sure that you have bottommed them out in the stud holes.

I'm not sure if you should use red or blue loctite. I guess red would be fine as long as there isn't any danger of screwing up the threads or breaking the stud off.

Does anyone know what size these bolts are? My local dealer was absolutely no help, except to tell me they had them in stock for $3/each! It seems to me that 1) that's kind of expensive for something I could get at a hardware store for $.10, and 2) kind of a long way to drive to get it (they're across town from me).
I was finally able to get under the car to see the manifold (I was moving last week and didn't really have the time), and discovered there are 3 of them missing!! I know from reading the posts here that this is common, but this seems kind of crazy! Also, now that I see them, it seems like a kind of crappy set up. Has anyone replaced these with a different style of bolt that doesn't fall out or come loose?
Finally, I'm wondering how bad it is for the engine to drive it like this. It makes an awful noise, but I don't know what if any damage I may be doing in the interim. As a precaution, I've stopped driving it other than when I have no option not to, but I was just curious if I should park it until these bolts are replaced.

Thanks for any input you may have!!
-Steve
